John Gruber has found out that cross-compilers are no longer allowed in iPhone OS 4.0. "My reading of this new language is that cross-compilers, such as the Flash-to-iPhone compiler in Adobe's upcoming Flash Professional CS5 release, are prohibited. This also bans apps compiled using MonoTouch - a tool that compiles C# and .NET apps to the iPhone. It's unclear what this means for tools like Titanium and PhoneGap, which let developers write JavaScript code that runs in WebKit inside a native iPhone app wrapper. They might be OK."

Right, if you read the comments on that link you find out that XBLA in fact has tons of non-exclusive games, MS just doesn't want to publish (i.e. promote) games that are not exclusives, which makes sense - that doesn't stop other from doing so. Not to mention the normal (DVD-based) games where non-exclusive titles make up a huge proportion, and which are the gaming experience people usually think about first with platforms like XBox, PS3. Last I heard, Apple is not signing a promotional contract for every App in the AppStore, that's up to the developer.

Also notice that Microsoft doesn't care what programming language or tools you use for your game.

I hate MS for all the wrong and right reasons, but I have to agree with you. XBLA is not the ONLY distribution channel for XBox, but AppStore is the only distribution channel(The one that was so hailed as the most wonderful thing that iPhone has).
